Setting 0 % and 100 % Output Parameters For current output, the Calibrator assumes that 0 % corresponds to 4 mA and 100 % corresponds to 20 mA. For other output parameters, 0 % and 100 % points must be set before using the step and ramp functions. Proceed as follows: M 1. If necessary, press for SOURCE mode. 2. Select the desired source function and use the arrow keys to enter the value. This example is temperature source using 100 °C and 300 °C values for source. 3. Enter 100 °C then press and hold J to store the value. 4. Enter 300 °C then press and hold G to store the value. This setting can now be used for the following: • Manually stepping an output in 25 % increments. • Switch between the 0 and 100 % span points by momentarily pushing J or G. Multifunction Process Calibrator Setting 0 % and 100 % Output Parameters % Error Functionality Percentage Error is available for every range on the lower display. The calculation is based on a mA percentage deviation from the value measured on the upper display to the value sourced on the lower display 0 % mA and 100 % mA are fixed to 4 and 20 mA. 0 % and 100 % for the lower display are set in source using J and G, refer to "Setting 0% and 100% Output Parameters". Stepping and Ramping the Output Two additional features are available for adjusting the value of source functions: • Stepping the output manually with the H and I keys, or in automatic mode • Ramping the output Stepping and ramping apply to all functions except pressure, which requires use of an external pressure source. 41

Setting 0 % and 100 % Output
Parameters
For current output, the Calibrator assumes that 0 %
corresponds to 4 mA and 100 % corresponds to 20 mA.
For other output parameters, 0 % and 100 % points must
be set before using the step and ramp functions. Proceed
as follows:
1.
If necessary, press
M
for SOURCE mode.
2.
Select the desired source function and use the arrow
keys to enter the value. This example is temperature
source using 100
°
C and 300
°
C values for source.
3.
Enter 100
°
C then press and hold
J
to store the
value.
4.
Enter 300
°
C then press and hold
G
to store the
value.
This setting can now be used for the following:
•
Manually stepping an output in 25 %
increments.
•
Switch between the 0 and 100 % span points by
momentarily pushing
J
or
G
.
% Error Functionality
Percentage Error is available for every range on the
lower display. The calculation is based on a mA
percentage deviation
from the value measured on the
upper display to the value sourced on the lower display
0 % mA and 100 % mA are fixed to 4 and 20 mA. 0 %
and 100 % for the lower display are set in source using
J
and
G
, refer to “Setting 0% and 100% Output
Parameters”.
Stepping and Ramping the Output
Two additional features are available for adjusting the
value of source functions:
•
Stepping the output manually with the
H
and
I
keys, or in automatic mode
•
Ramping the output
Stepping and ramping apply to all functions except
pressure, which requires use of an external pressure
source.
